Some 15 years ago, I lived in a local suburb called Sylmar, which was right up against the base of some foothills. Several times, we had bizarre hailstorms that smelled STRONGLY of fish! They were small, slightly gray, and made the whole neighborhood smell like a bait shop. The poor cat didn't know what to do, it drove her crazy!

When living in Chicago, I've had it rain 3 or 4" fish before. If an intense storm picks up water from Lake Michigan, it will pick up small fish. It's a pretty rare occurrence, I've seen it maybe 3 times in my life.
